+### reload
+
+exec's the current shell.
+if it's `zsh`, it'll recompile `.zshrc` so everything actually reloads.
+
+### ADDPATH
+
+adds a directory to `$PATH` if it isn't already there.
+
+### ify
+
+pipes a command through another command, so you can pass arguments at the end as usual.

+
+```
+$ alias ll="ify less ls -ACX --group-directories-first --color=force"
+$ ll /etc
+```
+
+### has
+
+prints the result of `which` if the program is found, or shuts up and returns 1.

+
+### revend

+
+### exts
+
+prints and sorts the most used file extensions in the CWD.
+
+### freq
+
+prints the most frequently used commands found in `~/.histfile`.
+arguments are passed to `head`.
